DLP Oracle 12c to Oracle 19c - can we do direct upgrade instead of migration?

    Hi All,

    As some of you noticed - there's no upgrade method for 12c to 19c mentioned in official guide. Any idea why is that?


    I remembered for 11g to 12c, we can use DBUA (upgrade assistance method)

    For Oracle 19c - there's only 'migration' option available



    a) Do we need to uninstall Oracle 12c first then only install 19c - since the instance/sid will be clashed ?
    b) Does the 'migration' actually indicate we're migrating to separate physical server for Oracle?



    Thanks

    Hello, our DBAs created a new DB from scratch and then imported data in all three environments - test / qa / prod.  not sure if that's what Oracle recommends or just the method they decided was best
